Are we entering an age when we will in effect end up with geo-fenced content filtering firewalls built on the back of that lovely catch-all `political correctness`. Look at the great firewall of China, how was that perceived initially and how is that perceived today. For some the perspective is still the same, for others, they see a more upfront way compared to how we are in effect seeing Governments implement comparable systems by forcing that filtering and content blocking/restrictions upon private companies. Whilst we are all for free speech and openness, we see governments all around the World curtailing those area's on the back of laws and regulations that are born out of a small minority and edge-cases. After all - seeing sites blocked on the net because 0.01% of the content falls foul of some law or regulation and that being classed as fine. Yet transpose that same mentality onto people and cries of discrimination and racism jump right out at you. Are we seeing the majority of people being sleep-walked into being firewalled upon what content they can see and what they can say akin to the great firewall of China? Sadly, I think we are.
